Claims.

This invention relates to new and useful improvementsin containers, and more particularly to an outlet for oil or gasoline containers and the like.

One of the objects of the invention is to provide an outlet for a container which is normally closed by a spring urged valve.

Another object of the invention is to provide a valve which when released opens communication between the container and an air chamber.

Another object is to provide an air inlet to the chamber.

Another object is to provide a container having a chamber provided with an air inlet adapted 5 to allow free flow of a liquid from the container through the outlet of the chamber.

With these and other objects in View the invention will be better understood by reference to the accompanying drawing and specification wherein like numerals represent corresponding parts and wherein:

Fig. 1 is a cross sectional view of the device and Fig. 2 is a top plan view.

Referring more particularly to the drawing l indicates a container having an opening 2 at the upper end thereof. Mounted at the inner face of the top wall 3 of the container 1 is a reinforcing washer 4. Mounted over the opening 2 is a dome 5 having a depending neck 6 adapted to be inserted through the opening 2 and peened as at l to the under face of the washer 4 whereby to lock the dome 5 to the container I.

The upper end of the dome 5 is internally threaded as at 8 to receive a closure 9. Arranged in a recess 9a formed in the closure 9 is a gasket 91) adapted to seal the upper end of the dome 5. The closure 9 is provided with a center bearing to adapted to slidably receive a valve 10 stem H. A gasket lflb is arranged in a recess Illa formed in the lower end of the bearing It The valve stem H has a valve l2 attached at its lower end which is adapted to rest upon a valve seat l3 formed in the lower wall M of the dome 5.

45 The dome 5 is provided with an outlet I5 at one side thereof to which a flexible spout or the like may be threaded if desired. An air inlet is provided at the other side of the dome as shown at It. A compression spring I! is mounted around 59 the stem l l with its upper end in abutment with the gasket ltlb and its lower end against the upper face of the valve l2. The gasket lob serves to prevent leakage of liquid through the bearing H). A compression spring I8 is mounted between 55 the closure 9 and the valve I2.

Pivotally connected at one side of the dome 5 as shown at i9 is a lever 28. The lever 28 is connected as shown at 2! to any suitable toggle connection 22. The forward end 23 of the lever it is forked and provided with a downwardly i ss curved portion 23a arranged below the rollers 24. Theupper end of the stem His rectangular as shown at Ha. Rollers 24 are pivotally mounted at the upper end of stem 1 l as shown at llb.

The operation of the device is as follows: 10

When it is desired to pour the liquid from the container I the lever 26! is pivoted backwardly by the toggle 22. The curved surface 23a rides under the rollers 2 raising the valve l2 against the action of the spring l8. Air is admitted into 5 the dome 5 through the inlet it. As the container is tipped to pour out the liquid through the outlet l5, air passes from the dome into the container thereby allowing for a free flowing of the liquid.

From the foregoing it will be seen that I have provided a simple and efiicient device and it is to be understood that various changes in the details may be made without department from the spirit of the invention. 5

When it is desired to fill the container l the closure 9 is unthreaded clear of the dome 5 and moved sidewardly.

Having thus described my invention what I claim is: 30

1. A container having an opening at one side thereof, a dome mounted in said opening, a valve mounted in said dome, said valve having a rectangular upper end, rollers mounted on said end, a lever pivotally mounted on said dome, said 5 lever having a forked forward end adapted to slidably receive the upper end of said valve, said forked portion being curved and adapted to ride beneath said rollers, a spring mounted in said dome adapted to close said valve, and means for moving said lever against the action of said spring.

2. In a device of the class described, including in combination, a valve body having an open top, an outlet, a valve seat, a disc mounted on said seat, a plug threaded into said body adapted 'to close said top, a sleeve extending inwardly from said plug, a valve stem attached to said disc extending through said sleeve, an expansion spring mounted over said sleeve in abutment with said plug and said disc, said sleeve having a recess in the lower end thereof, a gasket mounted in said recess, and an expansion spring mounted around said stem between said gasket and said disc.

3. In a device of the class described, including in combination, a valve body having an open top, an outlet, a valve seat, a disc mounted on said seat, a plug threaded into said body adapted to close said top, a sleeve extending inwardly from said plug, a valve stem attached to said disc extending through said sleeve, an expansion spring mounted over said sleeve in abutment with said plug and said disc, said sleeve having a recess in the lower end thereof, a gasket mounted in said recess, an expansion spring mounted around said stem between said gasket and said disc, a forked lever pivotally mounted on said body, said stem having a rectangular upper end extending through said forked portion, rollers mounted on opposite sides of said rectangular end, said forked portion being curved downwardly and adapted to ride beneath said rollers, and means for rocking said lever whereby to open said valve.

4. In a device of the class described including in combination, a valve body having an opening in its lower end, an annular extension formed on said lower end, a container having an opening therein, said extension adapted to be peened in the opening of said container, a valve body having an open top, an outlet, a valve seat, a disc mounted on said seat, a plug threaded into said body adapted to close said top, a sleeve extending inwardly from said plug, a valve stem attached to said disc extending through said sleeve, an expansion spring mounted over said sleeve in abutment with said plug and said disc, said sleeve having a recess in the lower end thereof, a gasket mounted in said recess, and an expansion spring mounted around said stem between said gasket and said disc, and means for opening said. valve.

5. In a device of the class described, including in combination, a valve body having an open top, an outlet, a valve seat, a disc mounted on said seat, a plug threaded into said body adapted to close said top, a sleeve extending inwardly from said plug, a valve stem attached to said disc extending through said sleeve, an expansion spring mounted over said sleeve in abutment with said plug and said disc, said sleeve having a recess in the lower end thereof, a gasket mounted in 20 said stem whereby to form communication be- 25 tween said inlet and said outlet sleeve.
